Description
Technical Field
The invention belongs to the technical field of packaging materials, and particularly relates to anti-graffiti leatherette paper.
Background
The leather-filled paper is formed by attaching a resin layer on the surface of a paper base. Because of its flexibility and skin feel, it is widely used as a packaging material.
The leatherette paper can comprise polyvinyl chloride (PVC) leatherette paper, polyurethane (PU) leatherette paper, ethylene-vinyl acetate copolymer (EVA) leatherette paper and the like according to material distinction. The resin on the surface of the paper base has the functions of decorating and protecting the paper base, reducing the retention of dirt on the surface of the leather-filled paper or enabling the surface of the leather-filled paper to be easier to clean, and the surface of the coating is required to have lower surface tension, so that the self-cleaning property of the surface of an object is improved, and the anti-graffiti effect is generated.
At present, the anti-graffiti technology obtains a certain use effect based on the anti-graffiti performance of low surface energy resin such as organic silicon or fluorocarbon or inorganic mineral particles. Organic silicon, fluorine resin or inorganic mineral particles are mixed with other resins (such as acrylic resin) or physical solution of auxiliary agent to obtain oil-soluble paint product based on organic solvent. Although the method is simple and practical and has low cost, the components are only physically combined and lack necessary chemical bond connection, a homogeneous and tough coating film is difficult to obtain, and the active ingredients playing the anti-graffiti role are easy to free and migrate out of the film, so that the anti-graffiti performance is obviously reduced along with the prolonging of time, and even the anti-graffiti performance is completely lost. Although some anti-graffiti coatings attempt to solve this problem by using a treatment that chemically cross-links the coating, which overcomes the migration of the active ingredients to some extent, the large amount of organic solvents in the coating formulation is very harmful to the surrounding environment during production and use.
Therefore, the search for a leather-filled paper with graffiti performance becomes the focus of research.
Disclosure of Invention
In order to solve the technical problem, the invention provides an anti-doodling leatherette paper, which comprises the following structures: a paper base; an adhesive layer; a polyolefin layer. The polyolefin layer comprises 100 parts of polyolefin, 0.1-10 parts of polyorganosiloxane and 0.01-5 parts of auxiliary crosslinking agent. After the polyolefin layer is subjected to irradiation crosslinking, the crosslinking degree is 10-90 percent
The polyolefin used in the invention can form reactive free radicals in the radiation crosslinking process as active crosslinking points to perform crosslinking reaction with active groups in the polyorganosiloxane, the auxiliary crosslinking agent increases the reactivity to form a three-dimensional network structure with higher crosslinking density, the polyorganosiloxane material and the polyolefin material form chemical bond connection through crosslinking, and the organic silicon component playing a graffiti-resistant role is not easy to migrate because of the chemical bond connection with the main chain of the polymer, so that a homogeneous and tough surface is obtained, and the graffiti-resistant leatherette paper with better performance is obtained.

The above summary of the present invention is not intended to describe each disclosed embodiment or every implementation of the present invention. The following description more particularly exemplifies illustrative embodiments. At various points throughout this application, guidance is provided through a list of embodiments that can be used in various combinations. In various embodiments, the lists are provided as representative groups and should not be construed as exhaustive.
The invention provides an anti-doodling leatherette paper, which structurally comprises: paper base; an adhesive layer; a polyolefin layer. The polyolefin layer comprises 100 parts of polyolefin, 50-100 parts of rubber elastomer, 1-10 parts of reactive siloxane and 0.1-5 parts of auxiliary crosslinking agent. After the polyolefin layer is subjected to irradiation crosslinking, the crosslinking degree is 10% -90%.
In the leathered paper of the present invention, the paper substrate may employ a base for leathered paper known in the art. The paper substrate generally has suitable strength and toughness, which can be selected by one skilled in the art according to actual needs.
In some embodiments, the polyolefin is selected from one or more of polyethylene, ethylene and alpha-olefin copolymer, polypropylene, propylene and alpha-olefin copolymer.
In some embodiments, the polyorganopolysiloxane has a molecular weight greater than 500 and may have pendant chains that are one or more of alkyl, epoxy, alkenyl, hydroxyl, amino, or acrylate groups.
In some embodiments, the co-crosslinking agent is selected from one or more of diallylamine, diallyl sulfide, N-methylene bisacrylamide, ethylene glycol dimethacrylate, triallyl cyanurate, triallyl isocyanurate, trimethylolpropane trimethacrylate, tetramethylolmethane tetraacrylate.
In some embodiments, the adhesive layer material is a blend of EVA and a tackifying resin, the tackifying resin including one or more of rosin, rosin derivatives, terpene resins, terpene phenolic resins, C5-C9 petroleum resins, dicyclopentadiene resins.
The invention also provides a preparation method of the leather-filled paper. The leatherette paper can be prepared according to the preparation method. The preparation method of the leather-covered paper provided by the embodiment of the invention comprises the steps of modified polyolefin layer preparation, attaching and irradiation crosslinking.
In the preparation step of the polyolefin layer, all raw materials of the polyolefin layer can be uniformly mixed and then subjected to double-layer co-extrusion casting with an adhesive layer on the surface of the paper base to form the modified polyolefin layer. The modified polyolefin layer preparation step may be performed using equipment known in the art, such as an extruder. The extruder may employ a T-shaped flat die.
In some embodiments, the adhesive layer is pressure or heat bonded to the paper substrate to achieve a secure bond between the polyolefin layer and the paper substrate. The pressure for pressure bonding may be 0.1MPa to 2.5MPa.
In some embodiments, a heated roll may be used on the paper-based side. The temperature of the hot roll can be 80-200 ℃. By preheating the paper base, the adhesive force between the paper base and the polyolefin layer can be improved.
The crosslinking step comprises crosslinking the polyolefin of the polyolefin layer. In some embodiments, the leatherette paper preform may be radiation crosslinked. This gives the polyolefin layer the desired degree of crosslinking, i.e. the polyolefin layer is a radiation crosslinked polyolefin layer. Radiation crosslinking may be performed using alpha rays, beta rays, gamma rays, X rays, or neutron rays.
In some embodiments, the leathered paper is crosslinked by irradiation, the degree of crosslinking after irradiation being from 10% to 90%.
